Title: Deodorizing method of malodorous gas
Inventor: AIBE NORIO
IPC: C01B31/08
Filed: 1994-04-28
Abstract: PURPOSE:To efficiently remove malodorous gas produced from a sewage tank by disposing a honeycomb-shaped activated carbon in the flow passage of the gas between a sealed sewage tank and air. CONSTITUTION:A honeycomb-shaped activated carbon is disposed in the flow passage of gas between air and a sealed sewage tank such as a building pit and underground sewage tank. The honeycomb-shaped activated carbon used contains about >=30% active carbon and about 200-2500m<2>/g BET specific surface area. Or, such a honeycomb-shaped activated carbon is prepared by dissolving or dispersing a chemical such as urea and iodine in water or an org. solvent such as alcohol and then spraying the obtd. liquid on a honeycomb-shaped activated carbon or impregnating a honeycomb-shaped activated carbon with this liquid. Since this honeycomb-shaped activated carbon requires no maintenance, gives small pressure loss and allows gas to uniformly pass, efficient deodorization can be obtd.

Inventor: NIINO KIYONORI
IPC: B05D7/22
Filed: 1986-04-19
Abstract: PURPOSE:To remarkably improve the working efficiency for lining by replacing only the valve disk of a valve contained in a pipeline without detaching the valve then of with a tentative valve disk provided with a flow hole. CONSTITUTION:A bonnet 10 of the valve 9 is removed and a valve stem 11 and the valve disk are removed from a valve box 13 in a lining method for an installed pipeline using gaseous flow and lining material. The tentative valve 14 is then inserted into the valve box 13 in place of the valve disk and the tentative valve disk body 14 is held in the position of the valve disk while the valve is held fully closed. The tentative valve disk 14 has approximately the same size as the size of the valve disk and is provided with the flow hole 15 of the bore approximately equal to the bore of a fluid passage 13a in the position where the valve body 13 faces the passage 13a. The air flow and lining material are supplied to an accelerator and the gaseous mixture composed of both is ejected from a nozzle into the pipeline 1. The working efficiency for the lining is thus considerably improved.
